Character mistake: Several times in the episode, Christopher refers to his mother as a paranoid schizophrenic. But in the rest of the series, she's always referred to as a manic-depressive schizophrenic.

During his interrogation, Ken comments that he beat Christopher's impulsive violence out of him. But in "The Perfect Thanksgiving", he tells Erin's brother Michael that he never hit his children, choosing instead to destroy their self-esteem.

When Ken appears at the end of the episode and Tommy wets his pants, David Shatraw actually had relieved himself. The studio audience wasn't aware of it until he pulled his tie aside to look down at his slacks.
